Sunlight Photosynthesis: 6CO 2 + H 2 6 H 12 O 6 + 6O 2 In the above reaction, sunlight supplies the energy to convert carbon dioxide and water to glucose and oxygen.Hydrothermal vents, which are hot springs on the sea floor, support exotic chemical-based ecosys-tems.
Chemosynthesis. Most life on Earth is dependent upon photosynthesis, the process by which plants make energy from sunlight. However, at hydrothermal vents in the deep ocean a unique ecosystem has evolved in the absense of sunlight, and its source of energy is completely different: chemosynthesis. Chemosynthesis is the process by which certain microbes create energy by mediating chemical reactions. So the animals that live around hydrothermal vents make their living from the chemicals coming out of the seafloor in the vent fluids!
